PDF Architect is a focused Mac app for the PDF tasks you actually need. Open multiple files in tabs, reorder pages by dragging thumbnails, delete pages with a right-click, merge several PDFs into one, and export pages as image files. It also opens JPEG, PNG, TIFF, and other image formats directly — converting them to PDF pages on the fly. No subscriptions, no unnecessary features.
Open several PDFs at once and switch between them using tabs. The sidebar shows a file list with thumbnails and a page thumbnail grid, so navigating large documents or comparing files is quick and easy.
Switch to the Thumbnails panel in the sidebar and drag any page to a new position. Right-click a thumbnail to delete that page instantly. No dialogs, no confirmation steps.
With two or more files open, click the Merge button at the bottom of the sidebar — or use the Merge As option in the Save menu — to combine all open files into a single PDF, preserving the file order shown in the sidebar.
Use Save as Image to export every page of a PDF into a folder as individual image files. Pages with embedded JPEG images are extracted directly; all other pages are rendered as high-resolution PNG files at 300 dpi.
Click Open in the toolbar to select one or more files. PDF Architect accepts PDF files as well as common image formats including JPEG, PNG, TIFF, GIF, and BMP. Image files are converted to single-page PDF documents automatically so they behave the same way as any other file in the app. All open files appear as tabs across the top of the main view.
The Thumbnails tab in the sidebar renders a scrollable grid of page thumbnails for the current document. Drag any thumbnail to a new position to reorder pages — the move is applied immediately to the document in memory. Right-click any thumbnail to access the Delete Page option. The current page is highlighted with a colored border so you always know where you are.
When two or more files are loaded, the Merge button appears at the bottom of the Files sidebar and the Merge As option becomes available in the Save menu. Triggering either opens a save dialog to name and place the output file. Pages from each open document are appended in the order the files appear in the sidebar list — reorder files by dragging in the list before merging if needed.
The Save Options menu at the bottom of the window offers Save (overwrite the original file), Save As (write a new PDF to any location), and Save as Image (export each page as a separate image file to a chosen folder). If the source file was an image, Save automatically redirects to Save As to prevent overwriting. The image export routine detects embedded JPEG data and extracts it directly; other pages are rendered as PNG at 300 dpi.
Click the Open button in the toolbar and select one or more files. PDF Architect accepts PDF files and major image formats. Each file opens in its own tab, and the sidebar shows a file list with preview thumbnails.
Open the Thumbnails tab in the sidebar to see all pages as a grid. Drag thumbnails to reorder pages, or right-click to delete a page. To combine multiple files, use the Merge button at the bottom of the Files sidebar.
Click Save Options at the bottom of the window to choose how to save. Overwrite the original, save a new PDF copy, or export all pages as image files to a folder — whichever fits your workflow.
"Finally a PDF tool that doesn't try to do everything. I needed something to reorder pages and merge files, and this does exactly that without getting in the way. The thumbnail drag is smooth and responsive."
"I use this to compile scanned documents into a single PDF before sending them. Being able to open image files directly saves me a step. The Save as Image export is a bonus I didn't expect to use but now rely on regularly."
"The tab interface makes it easy to work with several PDFs side by side. Merging is one click once everything is loaded. Clean, fast, does what it says."
